07silverado5.3

hey guys i am new too the site and the ls style motor in general do alot of subaru stuff. So i have an 07 silverado 4x4 5.3 auto with 80,000 miles and looking too make it alittle more entertaining to DD. So far i have gibson tublar headers exhaust and intake with spacer. From what i have researched with a intake manifold, injectors, cam, heads and a good tune I can make decent power was wondering if i could hit 500hp with this and still be okay as a daily and will the tranny hold it? any input would be awesome forced induction isnt out of the picture just trying too make it n/a.

thanks

350rwhp is about max on a 5.3, streetable anyways

on the trans it depends if you have the 4 or 6 speed, 6 speed will be stronger

He has a 4 speed being an 07.

You'll be quite a ways away from your goal unless you go nitrous or forced induction. They can be stout motors n/a, but 500 likely isn't going to happen.

350rwhp wouldnt be bad i was thinking supercharger in a year or so but wanted to do head cams intake and fuel right now and was wondering how far that could get me and i do tow with the truck. Any brands or combinations i should lean towards?

It could happen BUT it will be VERY expensive and you will lose drivability. Just spray
